VISE.

Application filed November 29, 1920.

T 0 aZZ whom it may concern:

Be it known that I, DAVID A. lVILnIXsoN, a citizen of the United States, and resident of the city of Overland Park, county of St. Louis, and State of Missouri, have invented certain new and useful Improvements in Vises, of which the following is a specification, containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a. part hereof.

This invention relates to improvements in vises, and has for its primary object a vise provided with a rest so that a number of small articles can be evened up and clamped between the jaws.

A further object is to construct a vise having a guide for evening up small articles to be clamped between the jaws, which guide is removable from the vise when desired.

In the drawings- Figure l is a side elevation of my device;

Fig. 2 is a front view of the same;

Fig. 3 is a rear view;

Fig. 1 is atop plan view;

Fig. 5 is a side elevation of the guide retaining spring; and

Fig. 6 is a side elevation of the rear portion of the screw for operating the aws.

In the construction of my device, I provide a vise-consisting of a movable jaw 7 and a stationary jaw 8. These jaws are pivoted together at the pointindicated by the numeral 9. The jaw S is provided with a spring 10, the free end of which tends to force the movable jaw outward.

Secured to the stationary jaw is a bolt 11 which has a tongue 12 formed on its head. This is for the purpose of preventing the bolt from turning. The bolt 11 passes through the movable jaw and is provided with a thumb nut 13 by means of which the jaw 7 is operated.

Formed integral with the stationary jaw are projections 14: and 15. The projection 15 is provided with a screw-threaded boss 16, through which the screw 17 passes. This is for the purpose of clamping the vise to a table or work bench. The extension 14 is provided with the upwardly-extending flange 18. This forms a recess 19 in which the spring 20 is placed. This spring is higher at its center than at either end and its purpose is to hold the guide in extended or with- Specifieation of Letters Patent.

drawn position. The guide isU-shaped and has two prongs, 21 and 22, and the connecting portion 23. This connecting portion is bent at right angles to the prongs 21 and 22, and its central portion is depressed, as indicated by the numeral 24. The purpose of this is to have the portion 24 contact with the spring 20.

Through the rear portion 25 of the flange 18 is inserted a screw 26 which passes above the depressed portion 24 and is screw-seated in the stationary jaw of the vise. This holds the guide in position on the stationary jaw. The jaws of the vise are provided with open ings 27. These openings are so arranged that the prongs 21 and 22 will pass through both of the jaws and not hinder the operation thereof.

hen it is desired to file a number of small articles, such as latch keys or the like, the guide or gage is pushed forward to assume the position shown in Fig. 1, the pattern and a number of blanks placed thereon, and the jaws tightened. This will insure the leveling up of all of the key blanks.

Each of the jaws is also provided with a horizontal semi-circular recess 28 and a vertical semi-circular recess 29. The purpose of these recesses is to grip the shank of an ordinary door key when filing the same and hold it securely against any twisting tendency. When it is desired to remove the guide, the guide is moved back until it contacts with the rear wall 25 of the flange 18. The screw 26 is then removed and the gage can be withdrawn from the opening and removed from the vise.

The vise can also be used for ordinary work by merely pulling the guide back, as before mentioned. The ends of the prongs 21 and 22 will then be withdrawn into the head of the stationary member of the vise.

Having fully described my invention, what I claim is:

1. A vise comprising a movable jaw and a stationary jaw, a guide slidably mounted in said jaws and extending entirely therethrough, a bolt and a nut mounted thereon for operating the movable jaw, means for holding the guide to the vise, and clamping means carried by the stationary jaw for securing the device to a work bench.

2. A vise comprising a stationary and a movable jaw, abolt and a nut mounted thereshaped guide having its closed portion conon for operating the movable jaw, extensions tacting with the spring in the recess, and a formed integral with the stationary jaw, a screw extending through said recess for hold- 10 flange formed on one of said extensions, said ing the guide in position.

5 flange forming a recess, a spring located in In testimony whereof, I have signed my said recess, a U-shaped guide siidably exname to this specification. tending through both members, said U- DAVID A. WILKINSON.
